EJ is acting just like Nicole did when she was chasing after Daniel, but knew he was in love with Jennifer.

IDK, I think Daniel led Nicole on way more than Sami has strung along EJ (at least in this current round) -- especially with all that sex on the desk and his declarations that he was having feelings for her. Daniel just abruptly dropped Nicole pretty much out of the blue when he found out Jennifer was available. IIRC, he never once warned Nicole that he was still carrying a torch for someone else, so she was given every reason to believe that he was unattached. So, while her actions were OTT, I don't blame her for being confused. EJ, however, can be under no such illusion about Sami. That girl's got more attachments than a Hoover vacuum cleaner.

I will concede, though, that both Nicole and EJ come across as looking equally pathetic in their lame attempts at scheming. The scheming isn't even clever and entertaining. It's just kind of painful and boring.

I do think Daniel had feelings for Nicole, but he just loved Jennifer so much and felt like Nicole would leave him for Rafe at any moment that he eventually stopped caring about her as anything but a friend. Sami, I don't think she really has feelings for EJ. I think she is just doing this because of how he looks, and for her precious Sydney and Johnny.

IMO the tanned golden nugget loves himself only and has a fetish for hitting on his vulnerable patients.
